  • Thanks This worked.. details
  • I have edited your questions title and tags to include Jettison to try and attract the answer you are looking for.. details
  • @Afrin this one also work for simple query.. details
  • I like to confirm whether it is done purely using JETTISON?. details
  • I am using Apache CXF which supports JSON through Jettison.. details
  • @Prabhathkesav it works with collection and single element: URL_http://pastebin.com/j8RbYkc3 .. details
  • It seems that RESTEasy used to use Jettison for JSON serialization, but from what I've been reading they've switch to Jackson ... all of this has made googling for help pretty hit or miss.. details
  • Once the property is set to CODETERM1 then jettison output the values always as string whether the data type is string or int does not matter.. details
  • Create a system property - i.e System.setProperty("jettison.mapped.typeconverter.class", "org.codehaus.jettison.mapped.SimpleConverter"); So jettison uses simple converter and output values as string.. details
  • Take a look at this lovely code: CODESNIPPET_JAVA1 .. details
  • Not to mention it cannot handle nesting of any kind.. details
  • It is possible that Jackson will behave similar to Jettison with respect to the JAXB annotations I simply didn't have the time to try it.. details
  • This seems to be an implicit "feature" of Jettison; it tries to introspect the actual data and figure out what's the best type fit.. details
  • If the value is coming as 1234AS in this case returns with double quote.How to fix this and making sure its always has double quotes.. details
  • Jettison with json marshalling converting string data type to integer type, when value is numeric.. details
  • If the value is coming as 1234AS in this case returns with double quote.How to fix this and making sure its always has double quotes.. details
  • Please help .. details
  • Is their a good way to export a mixed HashMap list?. details
  • Thanks in Advance.. details
  • But I can not marshall a simple java object (which has no annotations in it) to Json using JETTISON.. details
  • But I like to get clear "Can we do it using JETTISON?. details
  • But I can not convert a simple java object which has no annotations like @XmlRootElement to JSON.. details

  • You could use Jettison (coming with Jersey) and prepare the structure you would like to have yourself using CODETERM1 and CODETERM2 as return values.They are in the package CODETERM3 of CODETERM4 which is a transitive dependency of CODETERM5 .. details
  • It must be** something like this(What I need) (Year:another values OR (Report:some valeus AND Citation:some valeues)) I tried with Jettison library and used DefaultMutableTreeNode to create the tree structure .. details
  • Your attempt is highly appreciated!. details
  • Thanks in advance.. details
  • but I can't get the above query.my result is like this CODESNIPPET_JAVA2 .. details
  • my main method look like this CODESNIPPET_JAVA4 .. details
  • if anyone can please help me.. details
  • I figured I would use URL_http://jettison.codehaus.org/ [Jettison] as it seems it would be URL_http://blog.bdoughan.com/2011/04/jaxb-and-json-via-jettison.html [easier- to-implement] since it actually works with JAXB; however, looking at URL_http://code.google.com/p/thrift-protobuf-compare/wiki/Benchmarking [Older- benchmarks] in which Jettison was not included I have found URL_http://code.google.com/p/kryo/ [Kryo] produces smaller files and Serialized and DeSerialized quicker than some alternatives.. details
  • EDIT: I guess i'm looking for what produces smaller files and operates faster.. details
  • EDIT: I guess i'm looking for what produces smaller files and operates faster.. details
  • Demo Below is some standalone code to demonstrate the reading/writing of the JSON.. details
  • check this: URL_http://stackoverflow.com/questions/2255220/how-to-parse-a-json - and-turn-its-values-into-an-array.. details
  • This provides the "write to file" (or to the standard output) solution.. details
  • Thanks for the answer and the extra effort!.. details
  • As an alternative to Jettison, your original JSON input can be easily parsed with URL_https://github.com/beckchr [StAXON] 's CODETERM2 , which works with any JAXB implementation: CODESNIPPET_JAVA4 .. details
  • We could eliminate this class if your JSON looked like: CODETERM5 .. details
  • Jettison is an interesting library but there are some issue you will encounter using it: URL_http://blog.bdoughan.com/2011/04/jaxb-and-json-via-jettison.html [ URL_http://blog.bdoughan.com/2011/04/jaxb-and-json-via-jettison.html ] Demo Only the standard Java SE APIs are used.. details

  • I've created a self-contained Maven project demonstrating this URL_https://github.com/zzantozz/testbed/tree/master/stackoverflow/8367671 -convert-xml-stream-to-json-stream [on-Github] .. details
  • So you are probably using one of legacy output methods (like jettison); meaning that if you configure system to use POJO mapping it should just work.. details
  • The output should be something like: CODESNIPPET_JAVA3 .. details
  • First, here is a working XMLEventReader: CODESNIPPET_JAVA1 .. details
  • Maybe I wasn't specifying the MediaType in the invocation of the service ;) thanks.. details
  • hey hi i didnt find in it can you give me link.. details
  • Thanks for the response.. details
  • Also, even without knowing this, users often ditch jettison as soon as they have tried Jackson ("pure" JSON) approach, and I think CXF also supports Jacksons (Jersey and RESTeasy do for sure).. details
  • Need more information -- what kind of Java object do you want to operate on?. details
  • Also, even without knowing this, users often ditch jettison as soon as they have tried Jackson ("pure" JSON) approach, and I think CXF also supports Jacksons (Jersey and RESTeasy do for sure).. details
  • POJO to XML** JAXB is the Java standard ( URL_http://jcp.org/en/jsr/detail?id=222 [JSR-222] ) for converting Java objects to/from XML (I am a member of the JAXB expert group): URL_http://bdoughan.blogspot.com/2010/07/jaxb-xml-binding-standard.html [ URL_http://bdoughan.blogspot.com/2010/07/jaxb-xml-binding-standard.html ] POJO to JSON** People have been using JAXB with URL_http://jettison.codehaus.org/ [Jettison] to produce JSON.. details
  • I strongly recommend ditching Jettison completely, and using the URL_http://docs.jboss.org/resteasy/docs/1.1.GA/userguide/html/json.html [RestEasy-Jackson-support] instead.. details
  • This seems to be an implicit "feature" of Jettison; it tries to introspect the actual data and figure out what's the best type fit.. details
  • It also URL_http://docs.codehaus.org/display/JACKSON/Jackson+JAXB+Support [supports- JAXB-annotations] just like Jettison.. details
  • I strongly recommend ditching Jettison completely, and using the URL_http://docs.jboss.org/resteasy/docs/1.1.GA/userguide/html/json.html [RestEasy-Jackson-support] instead.. details
  • If I change it to CODETERM2 the JSON response will treat it as a Sting and keep the double quotes in the response.. details
  • I am using Apache CXF which supports JSON through Jettison.. details
  • My starting framework is JBoss RESTEasy (JAX-RS implementation) that provides an elegant way to consume Rest services JSON services by mapping JSON to JAXB thru Jettison framework (it works also in the other way if you want to provide REST service and produce JSON from JAXB).. details
  • You could use the Jettison driver with XStream to serialize / deserialize string <-> json : URL_http://xstream.codehaus.org/json-tutorial.html [ URL_http://xstream.codehaus.org/json-tutorial.html ] I had used this sometime back - there are some caveats on how the json schema should be for the parser to parse perfectly well.. details
  • That's all, have a nice day!. details
  • I found XSteam useful when converting Objects back and forth between Java & XML or JSON with the Jettison driver.. details
  • I've been working with Apache Wink and for that I have needed to use a JSON provider, such as Jettison (a colleague has been using Jackson).. details
  • I've used URL_http://jettison.codehaus.org/ [Jettison] and it works well.. details
  • Actually, any XML package that can use Stax API can use Jettison -- JAXB does, so there's no extra work involved (same is mostly true for XStream too, although it may have some additional support).. details
  • Note however that XStream really is an XML-based object serializer; so while it does have JSON compatibility support, it goes through JSON->XML converter (Jettison) so any size or performance benefits JSON may have are lost.. details

  • [EDIT Update issues using URL_http://code.google.com/p/google-gson/ [GSON] library]I attempted to use the URL_http://code.google.com/p/google-gson/ [GSON-library] but it cannot deserialize concrete objects when I only have it expect generic super classes (XStream and Jettison handles this because type information is baked into the serialization).. details
  • JAXB 2.0 also has support for JSON serialization using Jettison.. details
  • "the java.io.IOException: Stream closed" exception that I'm getting happens when I use Jackson instead of Jettison.. details
  • "the java.io.IOException: Stream closed" exception that I'm getting happens when I use Jackson instead of Jettison.. details

  • also I can't see any bug in here.if it has please explain more.. details
  • But I need to implement it using JETTISON :( .Plz guide me to achieve this using JETTISON.. details
  • cxf uses jettison by default.. details
  • Jettison is another JSON driver and the default is XML.. details
  • I'm sure you will see the problems with it (raw access to generic objects, can only access public fields, sloppy exception handling).. details
  • All in all - very bad 'serialization' code.. details
  • JAXB (JSR-222) is configuration by exception and only requires annotations where you need to override the default XML representation (Jettison converts XML StAX events to/from JSON).. details
  • I am getting the following Exception when I try to marshall the java object to Json CODESNIPPET_JAVA1 .. details
  • Mapper transfers it logically to: The JAXB specification** itself does not cover JSON-binding so sometimes implementations are used with libraries like Jettison which converts XML events to/from JSON and problems occur such as collections of size 1 being represented incorrectly.. details
  • It is weird.. details
  • Json Response String is {"0":{"0":"Rockey","1":"John"}} I am using Apache CXF Framework with Jettison as the JSON Provider also uses JAXB to wire the data to low bandwidth clients.. details
  • Jettison seems to have a problem here.. details
  • Coming back to OP's original question, how do we solve this problem using Jettison?. details
  • Coming back to OP's original question, how do we solve this problem using Jettison?. details
  • Human readability can be sacrificed since I don't plan on reading the files only processing them .. details
  • How do I get rid of the ending "$": ""I read that the Jettison (which is the default JSONProvider implementation that I am using) is by default will represent properties mapped with @XmlValue as '$'s but there's no property ?. details
  • I have following exception: CODESNIPPET_JAVA3 .. details
  • The trick was to extend the JacksonJsonProvider (which we use in CXF to force it to use Jackson instead of Jettison) and tell it to bypass Jackson altogether when dealing with raw Strings: CODESNIPPET_JAVA1 .. details
  • Jackson does not depend on Jettison (or vice versa).. details
  • At which point you should have no problem writing code such as: CODESNIPPET_JAVA2 .. details
  • I'm getting this error Exception in thread "main" javax.xml.bind.UnmarshalException - with linked exception: [javax.xml.bind.UnmarshalException: unexpected element (uri:"", local:"appUsage").. details

  • Tools that can be used for converting from/to XML/JSON (e.g., URL_http://beckchr.github.com/staxon/ [StaxON] , URL_http://json- lib.sourceforge.net/ [JSON-lib] , URL_http://jettison.codehaus.org [Jettison] , URL_http://xstream.codehaus.org/ [XStream] ) do not seem to do that but only conversion of a known structure.. details
  • For clarity, my payload class looked a little like CODESNIPPET_JAVA2 .. details
  • Two important notes: 1) This code is provided as-is; specifically I have not thoroughly tested it beyond my own limited use, and 2) The fact that this problem is virtually non-existent elsewhere on the internet, as well as the fact that this seems to be a relatively basic operation that Jettison should perform, strongly suggests to me that we're doing something fundamentally wrong and that this solution shouldn't be necessary.. details
  • You may use the above source for any purpose, freely, at your own risk, but it would be nice (although not required) if you attributed it to me and linked to this page on stackoverflow.. details

  • However, you can make Jackson the default with some Spring xml config: URL_http://cxf.547215.n5.nabble.com/Overriding-the-default - Jettison-JSON-Provider-td1223554.html.. details
  • CXF's default JSON serializer is Jettison which adds the '@' symbols.. details
  • Isn't this a little perverse?. details
  • By default Jersey will use JAXB to process the JSON messages by leveraging the URL_http://jettison.codehaus.org/ [Jettison] library.. details
  • But a lot has happened since then; alas, given this history, most tutorials start with jettison (or xstream+jettison) approach and only then present Jackson approach.. details
  • As of this writing, there are these 20: URL_http://www.JSON.org/java/index.html [org.json] URL_https://github.com/upictec/org.json.me/ [org.json.me] URL_http://jackson.codehaus.org/ [Jackson-JSON-Processor] URL_http://json-lib.sourceforge.net/ [Json-lib] URL_http://developer.berlios.de/projects/jsontools/ [JSON-Tools] URL_http://code.google.com/p/json-simple/ [json-simple] URL_http://www.stringtree.org/stringtree-json.html [Stringtree] URL_http://sojo.sourceforge.net/ [SOJO] URL_http://www.restlet.org/ [Restlet] URL_http://jettison.codehaus.org/ [Jettison] URL_http://json-taglib.sourceforge.net/ [json-taglib] URL_http://xstream.codehaus.org/ [XStream] URL_http://code.google.com/p/jsonmarshaller/ [JsonMarshaller] URL_http://flexjson.sourceforge.net/ [Flexjson] URL_http://sourceforge.net/projects/jontools/ [JON-tools] URL_http://code.google.com/p/google-gson/ [google-gson] URL_http://argo.sourceforge.net/ [Argo] URL_http://pivot.apache.org/ [Pivot] URL_http://jwm.slavitica.net/p/projects/jsonij [jsonij] URL_http://sourceforge.net/projects/fastjson/ [fastjson] ...but of course the list can change.. details
  • This is how URL_http://jettison.codehaus.org/ [Jersey] (JAX- RS reference implementation) converts POJOs to JSON by default.. details
  • The problem is XmlValue would not take a user-defined type.. details
  • The problem is XmlValue would not take a user-defined type.. details
  • Sorry.. details
  • I think it is a bad idea to try treat JSON as if it was XML (which is what you are essentially asking); however, URL_http://jettison.codehaus.org [Jettison] does just this.. details
  • Ok, no solution found with Jettison (I'm convinced it's a bug) and JAXB mapping for JSON.. details
  • I don't know whether resteasy 1.1 containts jettison provider but version 1.2 does.Also if you are using jdk 1.6 you must exclude javax.xml.stream:stax-api jar file, otherwise you will have a problem.. details
  • actually I had the same problem, I did solve it by adding jettison provider for application/json mime type.. details
  • FWIW, XStream with Badgerfish (jettison) does handle them (since it's full object-serialization framework, although resulting json looks ugly, as its xml based, just converts to json via badgerfish).. details
  • So far, this is the story of a failure, and any advice is welcome.. details
  • So far, this is the story of a failure, and any advice is welcome.. details
  • For example this fails: CODESNIPPET_JAVA1 .. details
  • But the question itself is bit vague: while you can always convert from one to the othe (it is a very trivial thing to do really), XML and JSON are not equivalent: there is no one-to-one lossless generic mapping.Hence, the question is: what are you planning to do with results, how is resulting xml to be used?. details
  • One more possibility: Jettison, URL_http://jettison.codehaus.org [ URL_http://jettison.codehaus.org ] can expose Json via XML parsing interface (stax XMLStreamReader), which allows integration with systems that only understand XML.. details

      • I am getting the following Exception when I try to marshall the java object to Json CODESNIPPET_JAVA1 .. details
      • Jackson does not depend on Jettison (or vice versa).. details
      • This is how URL_http://jettison.codehaus.org/ [Jersey] (JAX- RS reference implementation) converts POJOs to JSON by default.. details

  • Bug: 8
    1. general: 8
      • "the java.io.IOException: Stream closed" exception that I'm getting happens when I use Jackson instead of Jettison.. details
      • also I can't see any bug in here.if it has please explain more.. details
      • I'm sure you will see the problems with it (raw access to generic objects, can only access public fields, sloppy exception handling).. details
      • Jettison seems to have a problem here.. details
      • I have following exception: CODESNIPPET_JAVA3 .. details
      • At which point you should have no problem writing code such as: CODESNIPPET_JAVA2 .. details
      • I'm getting this error Exception in thread "main" javax.xml.bind.UnmarshalException - with linked exception: [javax.xml.bind.UnmarshalException: unexpected element (uri:"", local:"appUsage").. details
      • The problem is XmlValue would not take a user-defined type.. details
  • Usability: 35

    2. jackson: 4
      • "the java.io.IOException: Stream closed" exception that I'm getting happens when I use Jackson instead of Jettison.. details
      • The trick was to extend the JacksonJsonProvider (which we use in CXF to force it to use Jackson instead of Jettison) and tell it to bypass Jackson altogether when dealing with raw Strings: CODESNIPPET_JAVA1 .. details
      • However, you can make Jackson the default with some Spring xml config: URL_http://cxf.547215.n5.nabble.com/Overriding-the-default - Jettison-JSON-Provider-td1223554.html.. details
      • But a lot has happened since then; alas, given this history, most tutorials start with jettison (or xstream+jettison) approach and only then present Jackson approach.. details
    3. jaxb: 2
      • JAXB (JSR-222) is configuration by exception and only requires annotations where you need to override the default XML representation (Jettison converts XML StAX events to/from JSON).. details
      • Ok, no solution found with Jettison (I'm convinced it's a bug) and JAXB mapping for JSON.. details
    4. class: 1
      • For clarity, my payload class looked a little like CODESNIPPET_JAVA2 .. details

      • All in all - very bad 'serialization' code.. details

      • Human readability can be sacrificed since I don't plan on reading the files only processing them .. details
      • Here's a trivial example using Java's built-in StAX implementation to URL_http://docs.oracle.com/javaee/5/tutorial/doc/bnbem.html#bnbfb [parse-XML] and Jettison to URL_http://jettison.codehaus.org/User%27s+Guide#User%27sGuide- STaX [produce-JSON] from it.. details
      • Tools that can be used for converting from/to XML/JSON (e.g., URL_http://beckchr.github.com/staxon/ [StaxON] , URL_http://json- lib.sourceforge.net/ [JSON-lib] , URL_http://jettison.codehaus.org [Jettison] , URL_http://xstream.codehaus.org/ [XStream] ) do not seem to do that but only conversion of a known structure.. details
      • You may use the above source for any purpose, freely, at your own risk, but it would be nice (although not required) if you attributed it to me and linked to this page on stackoverflow.. details

      • The problem is XmlValue would not take a user-defined type.. details
      • actually I had the same problem, I did solve it by adding jettison provider for application/json mime type.. details

    7. json: 9
      • Jettison is another JSON driver and the default is XML.. details
      • Mapper transfers it logically to: The JAXB specification** itself does not cover JSON-binding so sometimes implementations are used with libraries like Jettison which converts XML events to/from JSON and problems occur such as collections of size 1 being represented incorrectly.. details
      • Json Response String is {"0":{"0":"Rockey","1":"John"}} I am using Apache CXF Framework with Jettison as the JSON Provider also uses JAXB to wire the data to low bandwidth clients.. details
      • CXF's default JSON serializer is Jettison which adds the '@' symbols.. details
      • By default Jersey will use JAXB to process the JSON messages by leveraging the URL_http://jettison.codehaus.org/ [Jettison] library.. details
      • I think it is a bad idea to try treat JSON as if it was XML (which is what you are essentially asking); however, URL_http://jettison.codehaus.org [Jettison] does just this.. details
      • FWIW, XStream with Badgerfish (jettison) does handle them (since it's full object-serialization framework, although resulting json looks ugly, as its xml based, just converts to json via badgerfish).. details
      • But the question itself is bit vague: while you can always convert from one to the othe (it is a very trivial thing to do really), XML and JSON are not equivalent: there is no one-to-one lossless generic mapping.Hence, the question is: what are you planning to do with results, how is resulting xml to be used?. details
      • One more possibility: Jettison, URL_http://jettison.codehaus.org [ URL_http://jettison.codehaus.org ] can expose Json via XML parsing interface (stax XMLStreamReader), which allows integration with systems that only understand XML.. details
    8. resteasy: 1
      • I don't know whether resteasy 1.1 containts jettison provider but version 1.2 does.Also if you are using jdk 1.6 you must exclude javax.xml.stream:stax-api jar file, otherwise you will have a problem.. details
    9. properties: 1
      • How do I get rid of the ending "$": ""I read that the Jettison (which is the default JSONProvider implementation that I am using) is by default will represent properties mapped with @XmlValue as '$'s but there's no property ?. details
